Essentially, it's supposed to support this feature (bypassing the vor/loc converter)
but I can't find a pinout that lists how to get this signal...
I'm trying to figure out how to hook up a CDI that takes composite input, as the
only ones that don't are the really expensive Collins and King models.

| Subject: | Narco AT-165 Transponder wiring question |
I recently purchased a nice used Narco AT-165 transponder from a third party. Luckily,
it came with a harness. Unfortunately, it did not come with installation
instructions. The harness has a 23 pin connector on the transponder side and
a 15 pin connector on the altitude reporter side. Three heavier wires (I believe
16 ga.) are cut to about 4 inches in length, coming out of the 23 pin connector.
I am assuming these are the power leads, red (+14V), black (Grnd), and
yellow (?). That's my question; what should this yellow wire attach to? It comes
out of pin #12 on the connector. I can't seem to find any wiring instructions
on the internet for this 23 pin transponder.

Traditional avionics color coding makes the red wire power, the black
wire ground, and the yellow wire the dimmer.
Here=99s a link to the AT-165 installation manual. It says that
pin 5 is +13.75 V input, pin 11 is the 14 V dimmer, and pin 12 is
ground. Perhaps the yellow wire is going to pin 11 instead of pin 12?
And I think it may be a 24-pin edge connector, with 12 pins on each
side.
Hope this helps you get everything sorted out!

Narco did one thing right. All of their transponders use the same tray
and pin connections. So pinout for AT50 or 150 will work.
